Synthesis and characterization of 3,5 trifluoromethyl Tpm with a metal carbonyl complex

Tris(pyrazolyl)methane (Tpm) ligands have a central carbon with 3 pyrazole rings attached. These were discovered in 1970 and have since been synthesized with many substituents on the rings. Based on the parent structure, my goal was to synthesize a fluorinated Tpm derivative. By adapting existing procedures, I have synthesized a Tpm derivative with trifluorinated methyl groups in the 3 and 5 positions of the pyrazole ring. The fluorinated ligand is expected to be electron withdrawing and exhibit interesting chemistry when bound to a metal center. Future directions of the project will be discussed.
